Runway Holding Position Markings These show where an aircraft should stop when approaching a runway from a taxiway. They consist of four yellow lines, two solid and two dashed, spaced six or twelve inches (15 or 30 cm) apart, and extending across the width of the taxiway or runway.
There are three main types, to land and hold on the runway: Intersecting Runway: before the intersection with another runway that will have another aircraft taking off or landing. Intersecting Taxiway: before the intersection with a taxiway that will have other aircraft taxiing for takeoff or parking. Point on Runway: before a designated point ...
A runway incursion is an aviation incident involving improper positioning of vehicles or people on any airport runway or its protected area. When an incursion involves an active runway being used by arriving or departing aircraft, the potential for a collision hazard or instrument landing system (ILS) interference can exist.
Takeoff Hold Lights (THL): Red unidirectional lights in a double-longitudinal row, located parallel to runway centerline lighting. Runway Intersection Lights (RIL): Similar to THLs, but located on a runway, prior to intersection with another runway. On taxiways, Runway Entrance Lights (RELs) show that runways are not safe to enter or cross.
The PAPI should be located on the left-hand side of the runway at right angles to the runway center line, although can be located on the right-hand side of the runway if required. The red lights are always on the side closest to the runway. If the PAPI is on the right-hand side of the runway (non-standard), the red lights will be on the left.
Emission patterns of the localizer and glide slope signals Glide slope station for runway 09R at Hannover Airport in Germany. In aviation, instrument landing system glide path, commonly referred to as a glide path (G/P) or glide slope (G/S), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path ...

Runway end identifier lights (REIL [1]) (ICAO identifies these as Runway Threshold Identification Lights) are installed at many airports to provide rapid and positive identification of the approach end of a particular runway. The system consists of a pair of synchronized flashing lights located laterally on each side of the runway threshold.
